摘 要:利用视电阻率测井曲线的周期性对渤南油田沙三段中上部地层进行地层基准面旋回的划分对比后发现:该旋回界面与地层基准面由上升到下降期间可容纳空间单向增加的极限位置基本一致;地层基准面旋回的划分与测井分析相结合可以进行储层。特别是高渗透储层预测。<Abstrcat> The Bonan Oil Field located in the Jiyang depression, Shandong is the greatest oil field of low permeability in the depression. The oilbearing rock series are mostly made up of the second and third members of the Paleogene Shahejie Formation in the Bonan oil field, of which 0-9 sandstone beds in the middle and upper parts of the third member have been well documented, and may be divided into hierarchical stratigraphic baselevel cycles by using apparent resistivity curves. The interfaces between these baselevel cycles are consistent with those divided by increasing limits of accommodation. The findings in this study may provide an important basis for the prediction of the distribution of reservoirs, especially the highly permeable reservoirs.
关 键 词:测井曲线 地层基准面旋回 储层物性 渤南油田 视电阻率 油气勘探
